## Questions & Answers

**Q: Is this pipe perforated?**
A: The description says perforated, I did not see that when I bought 10 of them last year.  They definitely ARE perforated but I didn’t figure that out until past the warranty.  It will let a lot of water out before it gets to where you want it.  Waste of money!!!

**Q: is this pipe designed to be buried underground?**
A: I have buried mine no more than a foot below surface.  Works great.

**Q: Is this UV rated?**
A: Black drain pipe is UV resistant, but not UV proof. This will probably last 3-5 years, if not longer, in full sunlight before it becomes brittle.

**Q: How to expand video?**
A: I have expanded it only by holding it in my hands and then pulling the compressions apart. For most men it requires what I would judge as 'medium' strength and exertion. It might be difficult for women though. I hope this response helps you.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for what I needed them for. Shipping times took forever.
*by D***. on July 23, 2025*

Works great for what I needed them for. Perfect size and length. Shipping took about 3-4 weeks for me but not sure if they were in stock at time of purchase or not

### ⭐⭐⭐⭐⭐ Not the thickest plastic….!
*by M***A on March 6, 2024*

I bought this for my son to try at his home with water coming in to the basement when it rains. He had one on the downspout already and I figure try taking it further away and add these! We’ve had a couple of decent rainy days…so far, it’s been dry. The price was great to try this and see if it helped, but if it does work, he’ll need something thicker and sturdier. It was worth a try…just hoping it’s a solution for his foundation! He may get a few years out of these, at least. They are nice, and easy to use, just a weak plastic, so I’m giving 5 stars anyway.

### ⭐⭐⭐⭐ Moves alot of water
*by M***T on September 3, 2025*

Good for moving water away from your downspouts. Need gutter attachment connector.
